Time parameter: absolute time point Tabs and absolute time drift value Δ Tabs, wherein, Δ Tabs can be according to public in embodiment two
Formula calculates.Fig. 5 is that employing absolute time Cooperative Mode implementing procedure figure according to embodiments of the present invention (compensates community to initiate
Flow process), as it is shown in figure 5, the method comprises the steps:
Step S502:S-eNB sends community to T-eNB (s) and compensates preparation request, and message carries: target energy-saving cell little
District's mark, self desired energy-conservation/compensation perform absolute time Texpect, oneself send this message under local record simultaneously
Time t1；
If step S504:T-eNB (s) implements energy-conservation/compensation with being intended to the Texpect moment, then return to community to S-eNB and compensate
The success response of preparation request, and carry: self receive the time t2 of preparation request and self send the time t3 of response message；
If T-eNB (s) disagrees implements energy-conservation/compensation in the Texpect moment, then returning failed response message, failure cause is labeled as
Disagree the expected time；And oneself proposed absolute time Tproposal can be brought；Otherwise, return failed response message,
Failure cause is labeled as refusal.
If step S506:S-eNB receives the failed response message that reason is refusal, answer termination process；If the reason of receiving
For disagreeing the failed response message of expected time, then can reset Texpect according to Tproposal, again initiate to consult
Flow process；If receive is success response message, then according to self receiving the time t4 of response message and above-mentioned t1, t2,
T3 calculates each T-eNB absolute time drift value Δ Tabs relative to oneself.
If step S508:S-eNB receives all T-eNB (s) successfully response message, then send community to T-eNB (s) and mend
Repay request message, carry energy-conservation/compensation and perform absolute time Tabs and corresponding T-eNB and the time drift amount between oneself
ΔTabs；(note: Tabs is generally equivalent to Texpect, at least can not be early than Texpect).
Step S510:T-eNB (s) can return to community to S-eNB and compensate the response message of request.
Step S512: in S-eNB side, performs RF parameter adjustment (as increase is sent out at Tabs moment S-eNB to compensating community
Penetrate power etc.).
UE in energy-saving cell, before (the Tabs+ Δ Tabs) moment arrives, need to be switched to it by step S514:T-eNB (s)
Its community；Then T-eNB (s) closes energy-saving cell in (the Tabs+ Δ Tabs) moment.
Embodiment four
Providing a kind of cell energy-saving method in the present embodiment, the present embodiment combines above-described embodiment and therein is preferable to carry out
Mode, the present embodiment uses absolute time Cooperative Mode, and by energy-saving cell start flow, S-eNB represents the energy-conservation of start flow

Time parameter: absolute time point Tabs and absolute time drift value Δ Tabs, wherein, Δ Tabs can be according to public in embodiment two
Formula calculates.Fig. 6 is that employing absolute time Cooperative Mode implementing procedure figure according to embodiments of the present invention (initiate by energy-saving cell
Flow process), as shown in Figure 6, the method comprises the steps:
Step S602:S-eNB sends cell energy-saving preparation request to T-eNB (s), and message carries: target compensation community little
District's mark, self desired energy-conservation/compensation perform absolute time Texpect, oneself send this message under local record simultaneously
Time t1.
If step S604:T-eNB (s) implements energy-conservation/compensation with being intended to the Texpect moment, then return cell energy-saving to S-eNB
The success response of preparation request, and carry: self receive the time t2 of preparation request and self send the time t3 of response message；
If T-eNB (s) disagrees implements energy-conservation/compensation in the Texpect moment, then returning failed response message, failure cause is labeled as
Disagree the expected time；And oneself proposed absolute time Tproposal can be brought；Otherwise, return failed response message,
Failure cause is labeled as refusal.
If step S606:S-eNB receives the failed response message that reason is refusal, answer termination process；If the reason of receiving
For disagreeing the failed response message of expected time, then can reset Texpect according to Tproposal, again initiate to consult
Flow process；If receive is success response message, then according to self receiving the time t4 of response message and above-mentioned t1, t2,
T3 calculates each T-eNB absolute time drift value Δ Tabs relative to oneself.
If step S608:S-eNB receives all T-eNB (s) successfully response message, then send community joint to T-eNB (s)
Can request that message, carry energy-conservation/compensation and perform absolute time Tabs and corresponding T-eNB and the time drift amount between oneself
ΔTabs；(note: Tabs is generally equivalent to Texpect, at least can not be early than Texpect).
